The only victim of the attack who has been publicly identified is 37-year-old Harold Brown Jr., a father of three. The base chief, a woman in her 30s, was also killed, according to current and former intelligence officials. She is believed to have been focused on al Qaeda since before 9/11. A former U.S. official says a second woman was also killed in the attack, and that both women had "considerable counterintelligence experience."
The attack also killed Captain Al Shareef Ali bin Zeid, a member of the Jordanian spy agency Dairat al-Mukhabarat al-Ammah, according to people who have spoken with bin Zeid's family. The Jordanian military released a statement acknowledging bin Zeid had been killed in Afghanistan, but did not mention he was working with the CIA.
The ability for the CIA to replace the officers and institutional knowledge taken away by the attack will help decide the war in Afghanistan, former intelligence officials argue.
CIA historian Tim Wiener says, "The war we are in is going to be won or lost by the quality of intelligence the CIA can gather in the field."
